In Classical architecture, what is an architrave?

The architrave is defined as the bottom portion of an entablature in Classical architecture. It is the horizontal beam that sits directly atop the columns and serves as the first major element of the entablature, which typically consists of three main parts: the architrave, frieze, and cornice. In this context, the architrave plays a critical role in distributing the weight of the structure above, providing structural support, and visually connecting the columns to the decorative elements that follow in the entablature.

Understanding the architrave's placement and function is essential to grasp the overall design and aesthetic of Classical buildings, as it sets the tone for the proportions and decorative details that accompany it. The architrave's simplicity often contrasts with the more elaborate frieze and cornice, emphasizing its structural importance while also contributing to the overall harmony of the façade.
